Figure 2: Layer-by-layer growth dynamics of the vertical MoS2 structure at 400 °C.

From: Direct TEM observations of growth mechanisms of two-dimensional MoS2 flakes

Figure 2

(a–d) Time-resolved in situ TEM micrograph series at (a) 0 s, (b) 12 s, (c) 37 s and (d) 51 s. Frames captured from Supplementary Movie 1. 4L, 5L and 6L stand for four-layer-, five-layer- and six-layer MoS2 structures, respectively. Coloured sketches are included to illustrate the MoS2 layers. Time listed for all figures is relative to the beginning of Supplementary Movie 1. Scale bars, 5 nm. (e) Schematic illustrations of the growth process at room temperature (left panel) and 400 °C (right panel).
